I have several 50mm lenses I use on my canon cameras (with adaptors).
Canon EF 1.2L USM and 1.8 ii, SMC Pentax 1.7and 1.4, Nikon 50 1.8, Carl Zeis (Contax) Planar t* 1.7 and 1.4, Leica Summilux-R 1.4 and XR (Ricoh) Rikenon 1.4.
I have seen tests comparing most of these excepting the Ricoh most put the Zeis out front but I personally have found the best is the Ricoh 1.4 then the Zeis 1.7 (which from what I have seen always tests better than the 1.4) then the Leica. I would like to see the test data (CA fringe and MTF-50 etc) on the Ricoh. Bokeh i think is a personal thing and the Ricoh seems to blur the background with less brightness in the edges than the other lenses. I like the colors of the Ricoh when using film over the other lenses. I think Ricoh fluked an exceptionally good lense by not going overboard in trying to correct things in the lens structure. Not sure if 8 aperture blades make any difference to lenses they do not mention that part of the lens in tests.
The best value for money so far for me has been the Canon 1.8 ii cheap but holds it own, good to leave in the car with the 50e not too much to lose if it gets stolen.
I have not tried Voigtlander Topcor 58 /1/4 and not seen any test I wonder how good it is? Olympus Zuko are supposed to be pretty good as well.
Pentax lenses vs Rikenon.
